HÜSKER PÖLL: Warehouse - Songs and Stories

Any deep Husker fans know of any earlier reverse reverb examples prior to "No Reservations"?

And what the hell is "stun guitar" anyway? The only other place I've seen it referenced is on Blue Oyster Cult album credits.

There's a guitar part during the intro to Eiffel Tower High that sounds a bit reverse reverbish

Also Don't Know Yet off Flip Your Wig has a lot of backwards guitar but whether or not that's rev reverb I don't know. They obv played the tape backwards for the cymbals though
